ABSTRACT:
The pump comprises a chamber divided into a lower cavity occupied by the fluid and an upper cavity at atmospheric pressure. A flexible ring piston sealingly runs in the chamber and is inserted in a slidable way on a stem valve, with which it co-operates to enable or interrupt the outward flow of the fluid. The piston has a tapered section at its lower end, which engages by friction in a corresponding tapered groove of the stem valve to allow delivering of a fine mist with a very low delivery pressure also.
